Then you can write for $stop in x::node()[PRED][1] return x::node()[.<<$stop] substituting >> if it's a reverse axis. If you want to include the stop node, return (x::node()[.<<$stop], $stop) It's not vastly elegant - this is one of those things that could have been done so much better with higher-order functions - but it's workable. It's not too difficult to optimize, either, though Saxon doesn't attempt this currently. Michael K
